OIL'ING srsrnm rca wINnmLLs.

Application led July 28, 1923. Serial No. 654,418.

To all whom .it may concern:

Be it known that I, FREDERICK RITZ, a citizen of the United States, residing at Napoleon, in the county '0f- Henry'and State of Ohio,lhave invented certain new and useful Improvements in Oiling Systems for Windmills; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in oiling system for windmills or wind-motors, and more especially' to a self contained construction which will positively lubricate the movable parts of the motor.

The various features of novelty and invention will appear from the detailed del scription taken in connection with the accompanying drawings forming part of this specification, and will be particularly set forth in the appended claims. y

Fig. 1 is a side elevation partly in section of my improved motor for windmills showing one form of motor to which the 'invention is applied.

Fig. 2 is a side elevation partly in section of a di'erent form of motor for windmills provided with my improved lubrication system. A y

Fig. 3 is a plan view of the motor illustrated in Fig. 1 of the drawings, and

Fig. 4 is a plan view of the motor illustrated in Fig. 2 of the drawing.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In both forms of motor there is provided a tubular hub 1 adapted to be supported over the top of a tubular mast (not shown) Supported on the hub is an encasement or bowl l5 adapted to hold oil and support the workin parts of the motor. At one side of the ub 1 is a laterally extending hollow arm 2 within which is mounted a pair of pulleys 4- over which is trained a cable or chain 3 leading into the hub 1 from a vane (not shown) which is mounted on the encasement in any suitable manner, it being understood that the vane may be swung by means of the calble 3 by an attendant at the foot of the mast for bringing the vane into proper position when it is desired that the motor shall operate.

Rising from the bottom of the bowl or encasement 5 is an upright tubular member 6 through'whch passes the pump rod 7. The top of the pump rod has a.. head 20 which 1s connected to operating mechanism now'l to be described. The head 20 of the pump rod supports a shaft 19 on which is 16 at the top of said stan ard to a 'suitable anchorage poi-nt in the bowl as at 15.

In the 'form of motor shown in Figs. 1 and 3, the arm 18 is given a rocking motion by the iz'ollowing mechanism. ILxtendingy across the bowl 5 and mounted in suitable bearings 9 in the sides thereof is a shaft 8 to one end of which is secured the windmill wheel (not shown). Aiixed on the shaft is an eccentric 11 surrounded by an eccentric strap 11 which has an arm 12 extending therefrom. Said5 arm 12 is ivotally connected to the rocker arm 18 as y a wrist pin 23 extending across an opening in said rocker arm. It will now be seen that as the shaft 8 is rotated by the mill wheel the l pump rod 7 will be given reciprocatory movement. i

The mechanism for oiling the various parts of the motor will now be described. The bowl 5 is adapted to be'filled with oil to a suitable level which will be below the" 'will be taken up by the gear 13 and means are provided to utilize this oil so received on the gear 13 for lubricating the parts.

Disposed over and resting on the gearl 13 is the free end of a wiper orlever 24 which is pivoted on the shaft 16 at the top of a standard 17. Projecting from the wiper at an an le thereto is a linger 25 which overlies the adjacent end of the rocker arm 18 which is provided with channels 21 in its upper surface for the' purpose of conducting 011 be wiped on by the wiper vand run down therearwardly inclined finger 25 projecting therefrom and be received in the channels in `the rocker arm. The bearings of the rocker' arm on the shaft 16 receive oil from the channels therein through oil holes 22 in the hub of the arm; .'the pump rod connection through lateral ways 22 leading from the channels 21; and fthe pin bearing by similar lateral ways 22.

As the oil is received in the channels in the rocker arm it will flow one Way or the other depending on the inclination of the arm as will be readily understood.

The shaft bearings 9 will be suitably 1ubricated by oil splashed up by the eccentric and also by oil carried up by the gear 10.

ln the form of motor shown in Figs. 2 and 4 the wind wheel (not shown) is affixed to a shaft 30 extending through the oil bowl 5 and mounted in suitable bearing 31 in the side walls of the bowl. Aiixed on the shaft 3() isa pair of gears 32 adapted to mesh with larger gears 29 aixed on a shaft 28 which is supported between said gears 29 in a bearing 27 which may extend from the tubular port 6, the bearing being preferably braced by a member 26 leading to the end walls of the bowl.

rllhe ars 29 are provided with alined crank pins 38 on their outer faces. lPitmans' '37v connect .the crank pins with the shaft 19 art the top of the pump rod, the shaft being suiiiciently long to permit the pitmen to be mounted over the ends of the shaft.

The oilin s em includes meshed gears and 46, t e atter being 'in mesh with one of the crank pin gears 29.

The gears Ll5 and 4:6 are supported on a bracket 42 secured to the brace 15, -a shaft 4:3 being provided for gmr l5 and a shaft 4.4 for gear 46.

Gear 4:5 is wiped by the wiper 24 as a1- ready explained. l@il is Men up by gear 45 from gear 46 which takes it up from gear 29 as will now be readily understood. Thev oil on ear 45 is wiped ed by the wiper and direc by the linger 25 laterally of the wiper tothe channel 21 in the rocker arm from whence the oil is directed to the bearings at either end of the said arm.

The pump rod head has an oil delec'ting circular dange 20' below the rocker arm :i ,einem arm] is odset from the intermediate wrist pin connection with the eccentric arm 12 to the pump rod pivot and the connection or said arm with the shaft 16 on standard 17 vcomprises a pair of hubs at the ends oit a fork. ln lB ig. 4l the arm has a single hub through which the shaft 16 passes and the standard 17 is provided with spaced bearing instead.

Having thus described my invention what l claim as new and desire to secure by Letters Patent of the United States is:

1. ln a windmill, the combination with a supporting frame including 'an oil bowl of a. member pivotally supported at one end and having connection with a 'pump rod at its other end, means including mechanil mechanisms adapted to convey lubrimnt from the oil bowl to the pivot joints of said member for lubricating the same, said means including a gear and a pivotm wiper continually resting on said gear, said wiper ha ing means for conducting oil to the top ot said member.

2. lin e. windmill, the'combination with a supporting frame including an oil howl, of a member pivotally supported at one end and having connection with a pump rod et its other end, a gear adapt@ to receive oil from the oil bowl, a wiper continually resting on said gear, a lateral hnger on said wiper overlying said memlber, the ,latmr having an oil channel into which the oil wiped ed said gear b said wiper is received from said linger, sai channel leading to the pivot joints of the said member.

3. ln a windmill, the combination with a supporting frame having an oil bowl, or' a rocker arm pivotally support@ at one end and pivotally connected to a pump rod at the other end, means adapted to convey lubricant from said bowl to a level above said arm, said means including a r, a wiper pivotally support@ at one en and having its other end supported on said ear, and nieans for conducting oil from sai wiper to said arm, the latter having means for conducting the received oil to its pivotal bearlsn testimony whereof ll alma my signature.
